There are rumored details from Call of Duty: Modern Warfare 3 on Kotaku, whose "sources" (apparently neither "reliable" nor "close to the situation") describe the upcoming installment in the military shooter series to its predecessors. Word is the game will feature changes to killstreaks and perks, and they offer several specific examples. They also say the controversial Tactical Nuke killstreak will be removed, and that the game will not include a zombie mode, as that is a signature component of Treyarch's contributions to the Call of Duty series.
